Liangzi Lake（Chinese: 梁子湖; pinyin: Liángzǐ Hú）is a freshwater lake in China, it is located in the southeastern part of Hubei Province (rural area south of Wuhan), situated in the south bank of the middle reaches of Yangtze River. The lake is 304.3 km 2, with a drainage area of 3265 km 2, an elevation of 20 m, length 31.7 km and mean width 9.6 km (max 12.3 m). The shoreline of lake is highly indented.
Liangzi Lake appears to have two outlets. On the northers side of the lake, a small river or canal flows from Liangzi into Tangsun Lake (汤逊湖), and urban lake on the south side of Wuhan, which eventually drains into the Yangtze. On the eastern side of the lake, another river flows from Liangzi Lake toward Ezhou, where it enters the Yangtze as well.
The lake is rich in fish and it is the origin of Wuchang Bream.
Analysis of core samples extracted from the bottom of the lake allows scientists to measure the presence of metals such as copper, lead, nickel and zinc in the environment over the last several thousand ages; they provide evidence for the existence of mining and metal smelting in the region as early as 1500 BC, during the time of the State of Chu. (The Huangshi/Daye region east of the lake continues to be a mining and metallurgical center to this day.)
